How can I set an icon for my Android application?

    If you intend on your application being available on a large range of devices, you should place your application icon into the different res/drawable... folders provided. In each of these folders, you should include a 48dp sized icon:

    • drawable-ldpi (120 dpi, Low density screen) - 36px x 36px
    • drawable-mdpi (160 dpi, Medium density screen) - 48px x 48px
    • drawable-hdpi (240 dpi, High density screen) - 72px x 72px
    • drawable-xhdpi (320 dpi, Extra-high density screen) - 96px x 96px
    • drawable-xxhdpi (480 dpi, Extra-extra-high density screen) - 144px x 144px
    • drawable-xxxhdpi (640 dpi, Extra-extra-extra-high density screen) - 192px x 192px

    You may then define the icon in your AndroidManifest.xml file as such:

    <application android:icon="@drawable/icon_name" android:label="@string/app_name" >
    .... 
    </application>

    Add an application launcher icon with automatic sizing.

    (Android studio)

    Go to menu File* → NewImage Assets → select launcher icon → choose image file.

    It will automatically re-size.

    Done!

    It's simple.

    Now simply go to menu FileNewImage Asset. This will open a new dialogue and then make sure Launcher Icons is selected (Which it is by default) and then browse to the directory of your icon (it doesn't have to be in the project resources) and then once selected make sure other settings are to your liking and hit done.

    Now all resolutions are saved into their respective folders, and you don't have to worry about copying it yourself or using tools, etc.

    Don't forget "Shape - none" for a transparent background.

    Put your images in mipmap folder and set in manifest file... like as

     <application android:icon="@mipmap/icon" android:label="@string/app_name" >
     .... 
     </application>  
    

    App Folder Directory :

    Place your images in drawables folder under either of the three and set it like this.

    Code

    <application android:icon="@drawable/your_icon" >
    .... 
    </application>

    If you have an SVG icon, you can use this script to generate your android icon set.

    A bit old, but for future use:

    Define the icon for android application

    <application android:icon="drawable resource">
    .... 
    </application> 
    

    https://developer.android.com/guide/topics/manifest/application-element.html


    If your app available across large range of devices

    You should create separate icons for all generalized screen densities, including low-, medium-, high-, and extra-high-density screens. This ensures that your icons will display properly across the range of devices on which your application can be installed...

    enter image description here


    Size & Format

    Launcher icons should be 32-bit PNGs with an alpha channel for transparency. The finished launcher icon dimensions corresponding to a given generalized screen density are shown in the table below.

    enter image description here


    Place icon in mipmap or drawable folder

    android:icon="@drawable/icon_name" or android:icon="@mipmap/icon_name"

    developer.android.com/guide says,

    This attribute must be set as a reference to a drawable resource containing the image (for example "@drawable/icon").

    about launcher icons android-developers.googleblog.com says,

    It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density. For example, an xxxhdpi app icon can be used on the launcher for an xxhdpi device.

    Dianne Hackborn from Google (Android Framework) says,

    If you are building different versions of your app for different densities, you should know about the "mipmap" resource directory. This is exactly like "drawable" resources, except it does not participate in density stripping when creating the different apk targets.

    For launcher icons, the AndroidManifest.xml file must reference the mipmap/ location

    <application android:name="ApplicationTitle"
             android:label="@string/app_label"
             android:icon="@mipmap/ic_launcher" >
    

    Little bit more quoting this

    1. You want to load an image for your device density and you are going to use it "as is", without changing its actual size. In this case you should work with drawables and Android will give you the best fitting image.

    2. You want to load an image for your device density, but this image is going to be scaled up or down. For instance this is needed when you want to show a bigger launcher icon, or you have an animation, which increases image's size. In such cases, to ensure best image quality, you should put your image into mipmap folder. What Android will do is, it will try to pick up the image from a higher density bucket instead of scaling it up. This will increase sharpness (quality) of the image.

    Fore more you can read mipmap vs drawable folders

    After that we will get icon image in mipmap different formats like hdpi,mdpi,xhdpi,xxhdpi,xxxhdpi.

    Now goto AndroidManifest.xml

    <application android:icon="@mipmap/your_Icon"> ....</application>
